The top end of the water inlet pipe (4) is provided with an auxiliary water inlet hopper with a trapezoidal cross section, the top ends of the water inlet pipe (4) and the exhaust pipe (3) are both higher than the upper end surface of the top plate (204), a floating ball is arranged in the exhaust pipe (3), and the diameter of the floating ball is larger than the diameter of the exhaust pipe (3).

The air inlet end of the spiral air inlet pipe (6) is provided with an L-shaped auxiliary air inlet pipe (7), the L-shaped auxiliary air inlet pipe (7) comprises a horizontal pipe and a vertical pipe, one end of the horizontal pipe is fixedly connected to the spiral air inlet pipe (6), the other end of the horizontal pipe is vertically provided with the vertical pipe, the middle position of the vertical pipe is provided with a check valve (8), the check valve (8) is arranged, and gas can be introduced when water in the L-shaped auxiliary air inlet pipe (7) overflows.

The water outlet end of the water outlet pipe (5) is provided with a rotary cover (501), the inner side of the rotary cover is provided with internal threads, and the outer surface of the water outlet end of the water outlet pipe (5) is provided with external threads.

The method for detecting the influence of different carbon dioxide concentrations on water comprises the following steps:

step 1: acquiring a water sample at a destination;

step 2: taking out the device (no water exists in the device at this time), screwing down the rotary cover (501) of the drain pipe (5), and screwing the plug (9) to separate the plug head from the branch water inlet pipe (402) (the branch water inlet pipe (402) is communicated with the water inlet pipe (4)) to complete the early preparation of the device;

and step 3: pouring the water sample into the water storage tanks (2) until a plurality of water storage tanks (2) are full of water (at the moment, the positions of floating balls in the exhaust pipes (3) are higher than the top plate (204)), standing the water storage tanks (2) for 10-15 minutes after the water storage tanks (2) are full of water, and standing the water storage tanks (2) after the water storage tanks are full of water, so that the accuracy of the experiment is guaranteed;

and 4, step 4: taking three gas tanks storing carbon dioxide with different concentrations, communicating the carbon dioxide gas tanks with an L-shaped gas inlet pipe by using hoses, respectively opening the three carbon dioxide gas tanks, adjusting a flow valve, supplying carbon dioxide gas to a gas supply device at a set flow rate of between 0 and 0.4L/min, and keeping the flow rates of the three carbon dioxide gas tanks to be the same;

and 5: after the water sample is aerated for a set time, closing the carbon dioxide gas tank and closing the flow valve;

step 6: and (3) opening the rotary cover (501), respectively taking a part of water samples from the sub water storage tank (2), and respectively measuring the pH value, the DO concentration, the concentration of bicarbonate and carbonate, the concentration of COD, the concentration of sulfate radical, the total salinity, the total hardness, the concentration of ammonia nitrogen, the concentration of chloride ions, and the ion concentration of metal elements such as calcium, magnesium, potassium, sodium, lead, iron, manganese, chromium, copper, zinc and the like.

After use, the device is cleaned and the residual water in the device is emptied.
